We started discussing this in v1, but the discussion got sidetracked:
Is there a technical reason why you don't also allow 1M pages, which
may be useful in certain scenarios?
=A0=20

No, it was mostly a matter of the time I have had and machines easily
available to me for testing. =A0I don't know of a technical reason that
would prevent supporting 1M huge pages, but would want the tests in the
libhugetlbfs suite to pass, etc.

Ok. Do you think the kernel should be able to change the page size settings
in that case, or should we rely on whatever the firmware tells us it has
configured already?
